Abstract

Procédé et dispositif servant à pratiquer l'ablation d'au moins une partie du cornet du nez. L'ablation d'au moins une partie d'un cornet permet de diminuer la dimension de ce cornet. Les trois cornets du nez (inférieur, moyen et supérieur) constituent au moins une partie des trois méats du nez (inférieur, moyen et supérieur). La diminution de la dimension d'un cornet du nez permet de limiter ou d'éliminer l'obstruction d'un méat nasal. De ce fait, la circulation de l'air à travers le méat nasal est améliorée. Le dispositif comprend un cathéter comportant au moins un élément d'alimentation en énergie servant à pratiquer l'ablation. Le procédé consiste à placer le cathéter à travers une narine dans un méat nasal contigu à une surface d'un cornet et à transmettre à ce dernier, depuis l'élément d'alimentation en énergie, une énergie suffisante pour effectuer l'ablation d'au moins une partie du cornet. Cette énergie peut être une énergie haute fréquence, de micro-ondes, d'ultrasons ou un rayonnement laser. Elle est appliquée, soit au moyen de sondes sortant du cathéter et pénétrant dans le coeur du cornet, sans effectuer l'ablation de sa surface, soit au moyen d'autres techniques non invasives. Les paramètres relatifs à ce procédé sont l'impédance du tissu, la température et la quantité d'énergie. Un élément dilatable gonflé par électrolyte refroidit le site opératoire et permet à l'électrolyte de s'écouler à travers ses pores, l'électrolyte pouvant posséder des propriétés d'activité biologique, d'efficacité chimique ou des propriétés radioactives.
